GRAPE-PAPER MACHINE.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed November 12, 1914. Serial No. 871,763.

Toull whom it may concern:

Be it known that I, HENRY JOSEPHS, a citizen of the United States, residing at Green Bay. in the county of Brown and State of Visconsin, have invented certain new and useful Improvements in Grape- Paper Machines; and I do declare the following to be'a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for making crape paper and more particularly to the moistening rolls thereof.

. The main object of the invention is to provide a roller for a crape paper machine constructed for controlling the amount of moisture absorbed and retained by the paper being treated.

Another object is to provide a roller of this character which will always retain a certain amount of moisture sufiicient tomoisten the paper on both sides, irrespective of the heat produced by the hot liquid of the bath through which the metal calender roll travels and which imparts a preliminary moistening to'the paper before its passage between the rolls.

To accomplish these objects a roll is provided between which and the calender roll paper to becraped passes, said roll being so constructed that the desired tension may be placed upon the bearings thereof by suitable means for varying the pressure of the roll according to the character of the paper being treated. For instance when a light paper is being treated a heavier tension must be applied to the roller bearings than when a heavy paper is treated as the light paper takes moisture readily and with the necessary tension applied sufficient of the'moisture can be squeezed out so as to produce a superior crape.

With these and other objects in view, the invention consists of the novel features of construction, and combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the accompanying drawings: Figure 1 is a side elevation of a machine embodying this invention; Fig. 2 is a vertical section thereof.

In crape machines heretofore employed the calender roll which passes through the moistening bath is usually constructed of chilled iron fabric coated and the roller which revolves on this chilled iron roller and between which the paper to be craped is fed, is constructed either of metal, rubber or metal faced with rubber or analogous material. Rollers of this character when constructed of the materials above referred to when revolved upon the chilled iron moisture applying roll become heated and dried from the effect of the heat of the bath. This heat dries off the upper roll so that moisture is applied to the paper by the lower roll only and thus causes the paper to be imperfectly craped and it is to overcome this defect that this invention is devised.

In the embodiment illustrated, a frame 1 is shown of any suitable or desired construction to support the operative mechanism. Mounted in this frame 1 is a roll of paper P which roll turns in bearings in the frame 1. A pressure roll 2 is also journaled in the frame 1 and is constructed of wood which is an important feature of the invention as it permits tension to be placed upon the bearings thereof by suitable weights or springs as 3 which may be altered to vary the pressure of the roll 2 on a metal calender roll 4 to be described. The wooden roll 2 is shown larger than the metal roll and extends laterally beyond said metal roll so that a considerable area of the paper passing from the roll P around the roll 2,will be preliminarily moistened before it comes in contact with the moisture applying metal roll which occurs at the point of contact between'the peripheries of said rolls and beyond said point on the side opposite the moisture containing side of the roll 4. The roll 2 exerts pressure on the roll 4 and the paper passing between them at this point of contact, and squeezes out the moisture from the paper, according to the tension of the bearings of roll 2 so that a perfect crape is produced when the doctor scrapes the paper off the roll 4.

The metal roll 4 is arranged beneath the roll 2 and journaled in the frame 1 and is designed for taking up the liquid shown at 5, through which it passes, and being uncovered and very smooth, carries the proper amount of moisture to the paper, which passes between it and the roll 2 which is disposed above and contacts therewith. A trough or tank 6 is located beneath the calender roll 4 and contains the liquid bath in which said roll 4 re olves and this bath may be water or it may be a solution of coloring matter according to the nature of the paper being treated. The purpose of the liquid is primarily to dampen the paper being treated but if the paper is to be colored or treated in any other desired manner the liquid may contain a coloring or other material in solution and it is applied to the paper in the dampening operation. Arranged adjacent to and in contact with the side of the calender roll 4 is a doctor or detacher 7 the operative edge or face of which is positioned to impart the necessary crimping or craping effect to the moistened paper as it passes over the chilled roll 4 and is scraped up out of contact therewith by said doctor. Any suitable means may be employed for driving these rolls and suitable means may be employed for receiving the craped paper as it passes from the machine.

From the above description of the construction and arrangement of the machine shown in the drawings, its operation in producing crape paper will be readily understood and it will be seen that the .paper is led from the rolls P from either side as may be desired and passes around the wooden roller 2 and between said roller and the calender roller 4 and the tension on this wooden roller is so adjusted with relation to the roller 4 as to cause it to press thereon with proper pressure to apply the liquid taken from the tank (3 by said roller t to the paper on the roller 2 so that the paper is thoroughly saturated with said liquid; This moistened paper as is well known, clings or adheres to the face of the chilled roll 4 until it meets the operative edge of the doctor or detacher 7 against which it impinges and by means of which it is stripped from the face of the calender roller and assumes a crinkled or craped condition.

\Vhile I have thus shown the preferred arrangement of my invention it will'be apparent that the essential feature of construction resides in the fact that the roller 2 is constructed of wood to adapt it to maintain a'moistened condition at all times thereby insuring the proper moistening of the paper on both of its faces and which, although subjected to heat, will not dry out to such an extent as to cause it to fail to moisten the paper. Moreover the bearings of such a roll as above described may be properly tensioned by suitable weights or springs and the tension varied to adapt the machine for use with papers of varying qualities andvarying thickness and such a roll by properly moistening the paper adapts the machine to be run at a very rapid speed and yet produces a perfect crape paper.

I claim as my invention:

1. In a crape paper machine the combination of a supporting structure, a bath containing trough arranged therein, an uncovered metal roll mounted to revolve in said trough, a revolubly mounted wooden roll arranged above and with its periphery in contact with said metal roll, a doctor arranged adjacent said metal roll with its operative edge contacting therewith on the side opposite that which applies moisture to the paper and to the contacting points of the roll, said doctor being positioned to scrape up and crape the paper passing over said metal roll, means for supplying paper to said rolls, said wooden roll and paper supply means being so arranged relatively to each other that the paper passing from said supply means contacts with a sufficient area of said roll to impart a preliminary moistening to the paper before its passage between the contacting faces of the rolls; said rolls exerting a squeezing and moisture applying etl'ect simultaneously on the paper passing between their contacting points.

- 2. In a crape paper machine the combination of a supporting structure, a bath containing trough arranged therein, an uncovered metal roll mounted to revolve in said trough, a revolubly mounted wooden roll arranged above and with its periphery in contact with said metal roll, means for adj usting the pressure of said wooden roll on said metal roll to control the squeezing action of said rolls on the paper passing between them, and a doctor arranged adjacent said metal roll with its operative edge contacting therewith on the side opposite that which applies moisture to the paper and to the contacting points of the rolls, said doctor being positioned to scrape up and crape the paper passing over said metal roll, said wooden roll being larger than said metal roll and arranged to impart a preliminary moistening to the paper before its passage between the contacting faces of the rolls, said rolls exerting a squeezing and moisture applying effect simultaneously on the paper passing between their contacting points.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
